Administrators should promptly install the Windows cumulative update on their systems to prevent a security compromise, as this vulnerability is actively exploited in the wild.

Critical Flaws Addressed

CVE-2024-21322 – Microsoft Defender For IoT Remote Code Execution Vulnerability

This vulnerability, which has a CVSS base score of 7.2, is classified as critical for Improper Neutralization of Special Elements used in a Command (‘Command Injection’)

“Successful exploitation of this vulnerability requires the attacker to be an administrator of the web application. As is best practice, regular validation and audits of administrative groups should be conducted”, Microsoft said.

CVE-2024-21323 – Microsoft Defender For IoT Remote Code Execution Vulnerability

Microsoft Defender for IoT Remote Code Execution Vulnerability has a base CVSS score of 8.8.

For the IoT sensor to successfully exploit this issue, the attacker must be able to deliver a malicious update package over the network to the Defender.

The attacker first needs to establish their identity and obtain the required authorization to start the update procedure. 

“Successfully exploiting this path traversal vulnerability would require an attacker to send a tar file to the Defender for IoT sensor.”

Microsoft said that after the extraction process, the attacker could send unsigned update packages and overwrite any file they chose.

CVE-2024-29053 – Microsoft Defender For IoT Remote Code Execution Vulnerability

This is also a critical Microsoft Defender for IoT,  Remote Code Execution Vulnerability, with a CVSS base score of 8.8. 

Any authorized attacker can exploit this vulnerability. Admin or other advanced rights are not needed.

“An authenticated attacker with access to the file upload feature could exploit this path traversal vulnerability by uploading malicious files to sensitive locations on the server,” Microsoft.
